用visua c++实现双路视频采集功能，用到了osg以及图像采集的相关知识-Visua c++ Dual video capture function, use the OSG and image acquisition knowledge

首先收集视频，采集合适的视频序列，然后利用opencv技术将视频序列转化成帧图像，然后做相应的处理-First collected video, capture the appropriate video sequence, and then using opencv technology video sequences framing the image, and then make the appropriate treatment

一个图像采集程序，完全可以用，需要图像采集卡-An image capture program, can use, you need to frame grabber
